[CLOSED] 1THs 1kW 28nm Miner - $4200 - March 18th, BTC, Wire, Paypal - Last Call

[Cheshyr]

Although I did not get even units already'm not happy :/ it's cheating if they are only 4 modules are to be refunded the money because the units are too expensive especially if you do not go their overclock: (

We can talk via email, phone, or PM.

I got a unit before this batch with 5 modules.  How do I overclock it?

I'm not quite sure how to overclock these.  I would assume you need to SSH into the Rasp Pi and modify the cgminer config file, as mentioned by someone else in the thread.  Anyone else able to help here?

The instructions I got:

"As the machine does not open interface for overclocking settings, you need  modify the cgminer parameters listed in /boot/www/index.php, it is said that the hash rate could up to 1.2T with the sufficient power supply after overclocking. We are working on that to evaluate whether it is possible"

Thank you.  I will try to mess with it once I have the room cool down to 78 degree

1.2Th is impossible and the reason why you got no instructions on how to overclock the Dragon units is because it will go up in smoke if you push it (Cheap-ass components)

This is on your own risk: (aka hardcore miner mode)

How to overclock a Dragon 1Th unit:

Turn it off, then on again.
SSH into the pi
Locate the CGminer folder
Create a .sh , name it to whatever you want (nano Overclock.sh  <-- just a example)
Add:

Code:

sudo ./cgminer -o "1" -u 2 -p bac --no-submit-stale --tempCut 70 --real-quiet --queue 1 --cs 9 --stmcu 0 --diff 5 --api-listen --api-network --A1Pll 800

1: Keep the ", add pool adress
2: Wallet or Username, depends on which pool you use
800: Default clocksetting, you can push it to 850Mhz but no more.

Save the file
Now you need to install screen for the pi, to keep the resource running even when you logout of the pi.

Code:

sudo apt-get install screen
screen bash

Now you´re in screen
Locate the CGminer folder
Now you need to run the .sh

Code:

sh Whateveryounamedthefileas.sh

Press CTRL + A + D to close screen
You´re still connected to the pi via SSH.

Code:

Logout

Now you´re not connected to the pi anymore and your Dragon is running the chips in overclocked mode.
Don´t connect to the web frontend! (If you do, you need to start over from step 1 again)
Check your hash status via the pool.

IMPORTANT:

If you got the 32 chip version it´s already clocked to 900Mhz (Instead of more chips they used a little more expensive components to handle the over clock, but saved a bunch of money since the A1 is more expensive). DO NOT EVEN TRY TO OVERCLOCK. Add blades instead.

If you got the 40 chip version you can push it to 850Mhz as long as the unit is in a cold room. The 850Mhz setting makes the Dragon pull 1000-1100 watt, so don´t expect the stock PSU to survive to long (unless you got the 2x650w psu version) but should give you 50-100Ghz more to play with.

If you turn off the unit or experience power outtake, just start screen on the pi and run the .sh again and you´re back on over clocked chips again.

Say thank you and send me a beer here: 1Nm46UJo57NAuwA9XdAoaYQpUk4Phg2Ueu  

EDIT: Thanks for the beer anon! (I like beer, so keep it coming if you feel that this guide helped you to earn some more coins   )

Edit 2: Cleaned the how to up a little. Added some text so now anyone with a little knowledge should be able to over clock.  You can create multiple .sh for different Mhz settings and pools ex Eligius.sh, Bitminter.sh, Ghash.sh and so on.

Thanks for the guide JD!  Wish we were getting the 40 chip version..

Thank you!  Did you lose any dragons while tweaking them?

[JointDoctor]

No units, but 2 blades.
...and you´re welcome guys

You lost 2 blades?  So your hash rate is less now?  So it is risky to overclock the unit then.

Yeah, but no worries i got spares 
Keep the clocking on 850Mhz and the only thing you need to worry about is the PSU if you got the 1x1000w PSU modell.
Or just disconnect a PCI-E cable from 1 blade and connect another PSU to the blade.

If you got the 2x650w modell there´s nothing to worry about

Any luck getting single blades to replace them?  

From the photos I'm seeing around, it looks like the mining controller will handle 6 blades, so if there's a way to get extras that might be helpful to those of us who will be receiving 32-chip miners.

The 32 chip version is 4 blades. The MCU can handle 8 units, only ports for 6, together with the pi.
I don´t know how the manufacturer handle warranty for you guys but i´m a bulk buyer so i get extra blades to avoid expensive RMA shipping (My deal says that the vendor is responsible for all shipping cost when it comes to RMA and warranty).

I wasn't thinking warranty, I was thinking more along the lines of buying another card or two and upping the power to get 1.2-1.4 TH/s.

Fully doable, just connect the blade/blades to the MCU and power (If you got the 2x650w version just plug in PCI-E connector/connectors) and lay it/them down on the plexi glas area. Runs a little bit hotter then the other blades, like 2-3 degrees. 32 chip version + extra blade/blades = Adjust clock setting to 850Mhz to be on the safe side.

[gallery2000]

It is very helpful.  Can you tell me the default username and password.

[Cheshyr]

I have yet to find a source for the individual blades, and my vendor is being rather unhelpful.

I want to order 8 more blades to put into the 4 machines i ordered to give me a total of 6 per unit.  Anyone know if we can order the blade separately?

Maybe we can buy them from Jointdoctor

[varakunai]

Ya, JD hook us up with some blades and maybe a few joints..

Cheshyr is getting stonewalled by the vendor, sounds like they want to sell whole units only.  Maybe one of the other resellers or bulk buyers?

[Cheshyr]

I'm totally cool with buying blades from JD if he can supply them.

[JointDoctor]

I´m not "officially" allowed to re-sell the spare parts right now guys.
If Cheshyr can´t find some one i can try to talk to my supplier.

1T25 Ver. 1.1 8xA1 is the model you want.
